Persists in 2.6.29-rc3 Fixed in 2.6.31-rc3, commit 1feede014bf3c58f60b35f91dcd8a2f89b3908ad (I think).
Negotiated Gigabit speeds (>95 MB/s both ways via iperf). One of my Netgear switches caused the chipset to go into some sort of extended negotiation that never seemed to get to Gigabit; power-cycling the switch seemed to fix the problem.
However, ethtool output remains the same:
Supported ports: [ TP MII ]
Supported link modes: 10baseT/Half 10baseT/Full
100baseT/Half 100baseT/Full
Supports auto-negotiation: Yes
Advertised link modes: 10baseT/Half 10baseT/Full
100baseT/Half 100baseT/Full
Advertised auto-negotiation: Yes
Speed: 100Mb/s
Duplex: Full
Port: MII
PHYAD: 0
Transceiver: internal
Auto-negotiation: on
Current message level: 0x00000037 (55)
Link detected: yes
But dmesg reports the correct speed:
[ 17.223186] ADDRCONF(NETDEV_UP): eth0: link is not ready
[ 25.512014] eth0: mii ext = 0000.
[ 25.536010] eth0: mii lpa=cde1 adv=01e1 exp=000f.
[ 25.552007] eth0: link on 1000 Mbps Full Duplex mode.
[ 25.552456] ADDRCONF(NETDEV_CHANGE): eth0: link becomes ready

Latest working kernel version: Unknown Earliest failing kernel version: 2.6.22 Distribution: Debian lenny, amd64 Hardware Environment: HP MediaSmart Server Software Environment: 2.6.26 with small PHY patch Problem Description: I am unable to get the sis191 Gigabit Ethernet in my MediaSmart to talk to my Gigabit switch (Netgear GS605v2) at anything higher than 100Mbit Full Duplex. The same hardware running Windows Home Server and the latest drivers from SiS can auto-negotiate Gigabit speeds with the Netgear without issue. dmesg info: sis190 Gigabit Ethernet driver 1.2 loaded.
